The te-set-subtlv command sets TLV values for sub-TLVs that carry DiffServ-aware Traffic Engineering (DS-TE) attributes.
The undo te-set-subtlv command restores the default configurations.
By default, no TLV values are set for sub-TLVs that carry DS-TE attributes.
te-set-subtlv { bw-constraint bw-constraint-value | lo-multiplier lo-multiplier-value | unreserve-bw-sub-pool unreserve-bw-sub-pool-value } *
undo te-set-subtlv { bw-constraint [ bw-constraint-value ] | lo-multiplier [ lo-multiplier-value ] | unreserve-bw-sub-pool [ unreserve-bw-sub-pool-value ] } *
| Parameter | Description | Value |
|---|---|---|
| bw-constraint bw-constraint-value |
Sets the value of a bandwidth constraint sub-TLV. |
The value is an integer ranging from 19 to 254. |
| lo-multiplier lo-multiplier-value |
Sets the value of the Local Overbooking Multiplier (LOM) sub-TLV. |
The value is an integer ranging from 19 to 254. |
| unreserve-bw-sub-pool unreserve-bw-sub-pool-value |
Sets the value of the unreserved bandwidth sub-pool sub-TLV. |
The value is an integer ranging from 19 to 254. |
Usage Scenario
There are no unified standards for sub-TLVs that carry DS-TE attributes in non-IETF mode. To ensure interconnection between devices of different vendors, you need to manually configure TLV values for these sub-TLVs. After TLV values are configured for these sub-TLVs, the traffic engineering database (TEDB) is regenerated, and then TE tunnels are reestablished. The sub-TLVs can be sent only after TLV values are configured for them.
Precautions
IS-IS TE must be enabled using the traffic-eng command in this scenario.
